i did more than 30 arena/rend duns per day back when farming that stuff was still relevant.
On many days i did far more than 30 gv runs in zf.
I can easily see ppl farming mara/dm east/ZG more than 30 runs a day even now.
I could even more easily see even myself running into this cap when farming certain flowers in instances. Especially since its realmlocked, not character locked.
This restriction is definitely going to be noticable to certain players. Their freedom on how to play the game has been infringed upon. This sets a really bad precedent, what kind of gameplay will be the next in line to see a limit on how much you can do it?
